Course: Lecture Preview Course on Quantum Communication

In the full curriculum, the first lecture provides a comprehensive introduction to classical cryptography - covering symmetric and asymmetric approaches, key management systems, and integrity checks - and a intreoduction to foundational quantum physics concepts. You’ll learn about the differences between bits and qubits, the principles of superposition, photon polarization, entanglement, and even touch on quantum algorithms. This preview features the first video from the complete course, spotlighting polarization, superposition, and entanglement—three essential pillars in the realm of quantum communication. Enjoy this sneak peek into the fascinating world of quantum technologies!

This fact sheet introduces fundamental concepts of quantum mechanics, including superposition, qubits, polarization, entanglement, and the no-cloning theorem, highlighting their significance for quantum communication and cryptography.
Self-Check 1 Quiz

Every lecture in the full-length course is accompanied by a self-check to test the knowledge gained. Here, we would like to provide a quiz with a single sample question from lecture 1.

In the second lecture of the full length course the essential concept of randomness and its critical role in quantum cryptography is discussed.
The topics of Lecture 2 are the following:

Key Topics Covered

What is randomness, and how do we define it?

How can we test whether a process is genuinely random?

How do quantum processes provide a source of perfect randomness?

How can entanglement be leveraged to create shared randomness between two parties?

In this Preview we would like to present you the second video of Lecture 2 on "Quantum Randomness" with
Randomness in Quantum Processes
Quantum Random Number Generators (ideal and realistic)
Entanglement as source of shared randomness
Quantum Randomness
Factsheet - Lecture 2 - Quantum Randomness File

This fact sheet explains the concept of quantum randomness, contrasting it with classical randomness, and explores key principles such as the Heisenberg uncertainty principle, quantum entanglement, and Quantum Random Number Generators (QRNGs) for secure cryptographic applications.
